摘要
通过选取甘肃省的国家A级旅游景点作为研究样本,基于GIS技术,运用最近邻指数、K指数、热点聚类等方法分析162个A级景点的空间分布特征;运用栅格成本加权距离算法,计算A级旅游景点的空间可达性,并测算县域单元的整体可达性;利用空间关联方法分析了县域可达性的空间差异。结果表明:甘肃省A级景点的空间分布总体上呈现出聚集分布的特点,所有景点的平均可达性时间为68.76 min,60%的景点可达性在1h以内;可达性在全省的分布差异十分明显,可达性空间分布具有明显的交通指向性。
Based on an investigation of 162 National A-grade tourist attractions and using GIS and some quantitative analysis methods, the spatial structure of tourist attractions in Gansu Province were investigated, with their characteristics and distribution being discussed. Spatial accessibility of tourist attractions was calculated by using cost weight distance method. Then the spatial differences of county accessibility of tourist attractions were discussed by using ESDA. Results show that general scenic spots exhibit an aggregated distribution. Considering the accessibility, we found that the average accessibility is about 68.76 minutes, and the area where the accessibility of scenic spots is within 60 minutes reaches 60% , while the area where the accessibility is within 30 minutes accounts for 22.78% and the longest time needs 396 minutes. Distribution of the accessibility has pointed to traffic line. At county level,the estimated values of Moran＇s I is positive numbers using analysis of spatial association. All the test results indicate that tourist attractions and adjacent areas show strong positive correlation.
